raio SHARK (the capitalization is a trademarked logotype) is a computer-controlled radio designed by Griffin Technology. The radio connects the computer through a USB interface, which also supplies power to the radio. The device is shaped like a shark fin, which includes four internal LED lights attached to three pieces of clear plastic on each side of the device's case, two LEDs of which glow blue when plugged in, the other two of which glow red when recording radio.
